SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 736,474, dated August18, 1903. Application filed July 14,1902- Serial No. 115,573. (Nomodel.)

T0 aZZ whom it may concern.-

Be it known that I, EDGAR I-I. BAKER, a citizen of the United States,residing at \Vhitebird, in the county of Idaho, State of Idaho, haveinvented certain new and useful Improvements in Sash-l -asteners and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to sashfasteners; and it has for its object toprovide a simple and cheap construction of this nature which whenconnected to a sash will hold the latter at different elevations withoutthe use of the usual sash-weights and which fastener will be automaticin its operations and may be moved into and out of engaging position bymanipulation of the sash.

Other objects and advantages of the invention will be understood fromthe following description.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a view showing in elevation the rear face of thespacing-bead between the upper and lower sashes of a window and showingthe lower sash in section. Fig. 2 is a section taken longitudinallythrough the bead and including the sash and showing the fastening-cam inelevation. Fig. 3 is aview similar to Fig. 2, showing the upper end ofthe bead and illustrating the means for reversing the cam.

Referring now to the drawings, it will be noted that only one side ofthe window-sash and the window-frame is shown in order to permit ofillustration on a large scale. The window-frame is shown at 5 and hasthe usual head 6, which separates the upper and lower sashes, and in thepresent instance only the lower sash 7 is illustrated. In the side ofthe sash 7, and adjacent to the upper end thereof, is a casing 8, inwhich is mounted the rockshaft 9, having the cam 10 fixed to one end andlying in a recess in the inner face of the sash, so that the end of thecam may engage the head 6. The cam 10 has a finger 11, which normallydepends with its end against the rack-teeth 12, formed on the face ofthe bead. As the window-sash is raised the end of the finger rides overthe teeth, and when it is attempted to lower the sash the end of thefin-' ger or cam engages the adjacent teeth and holds the sash againstdownward movement. By this means the sash will be held at whateverelevation to which it may be raised.

\Vhen it is desired to lower the sash, it is of course necessary toreverse the cam, so that the end of its finger will ride over the teethin its downward movement. For this purpose openings 13 are formedthrough the head between each series of rack-teeth, and at the lower endof each of these recesses or openings 13 is journaled a roller 14:. Whenit is desired to lower the sash, the sash is raised until the free endof the finger of the cam swings over the roller. The sash may be thenlowered, and the cam by lying against the roller is moved to an invertedposition, and in the further downward movement of the sash it rides idlyover the rack-teeth. At the lower limit of movement of the cam with thesash is formed an opening or recess 15 in the bead, which the cam entersand is reversed by gravity, so that it moves again into position withthe finger depending and is ready to engage the teeth when the sash isagain raised to the proper height.

What is claimed i's 1. The combination with a window-casing having abead provided with rack-teeth and openings between certain of therack-teeth, of a window-sash having a cam mounted eccentrically thereonand having a finger disposed to move in contact with the teeth and enterthe openings interchangeably, the extremity of the finger being agreater distance from the axis of the cam than the face of the bead,whereby the cam will prevent dropping of the window when the finger isengaged with the tooth and whereby the cam may be rotated to permit thewindow to be lowered when the finger enters an opening;

2. The combination with a window-casing having a bead provided withrack-teeth and openings between certain of the rack-teeth, of awindow-sash having a cam mounted eccentrically thereon and having afinger disposed to move in contact with the teeth and to enter theopenings above the rollers successively, the extremity of the fingerbeing a greater distance from the aXis of the cam than the face of thebead, whereby the cam will prevent dropping of the Window when engagedwith a tooth and may be rotated When engaged with an opening each ofsaid openings having a friction-roller at its lower end for contact bythe finger. 10

In testimony whereof I affix my signature in presence of two witnesses.

EDGAR I-I. BAKER.
